Integrated Recommendation: Balanced at Low Volumes

I've been using a NAD c320BEE for a while and notice that it was not very balanced at low volumes which is where I do most listening. (I was very happy with it using just the amp section). I recently sold it and I'm looking for a replacement integrated. System is going to be as follows:

Macbook Pro (Apple Lossless files)
Assemblage DAC 2
Quad 11L2s

This is a nearfield desktop system so I don't need anything with a ton of power, a decent headphone amp and remote would be nice but neither is a deal breaker. I'd like to keep it <$1000 used. My main requirement is a good pre-amp section.

I'm considering:

Bryston B60R
Primare integrateds

Any other recommendations or thoughts? Thanks!
